In a two-centre study, 164 patients with unilateral instability of the anterior cruciate ligament were prospectively randomised to arthroscopic reconstruction with either a patellar tendon graft using interference screw fixation or a quadruple semitendinosus graft using an endobutton fixation technique. The same postoperative rehabilitation protocol was used for all patients and follow-up at a ...

BACKGROUND The optimal management of a torn anterior cruciate ligament (ACL) of the knee is unknown. METHODS We conducted a randomized, controlled trial involving 121 young, active adults with acute ACL injury in which we compared two strategies: structured rehabilitation plus early ACL reconstruction and structured rehabilitation with the option of later ACL reconstruction if needed. The pri...

BACKGROUND Patellar tendinopathy can be treated surgically for patients that have failed at least 1 year of nonoperative treatment who continue to have debilitating symptoms. Patellar tendinopathy can cause significant functional deficits, yet little has been reported about the operative treatment of patellar tendinopathy. HYPOTHESIS A combined arthroscopic and open surgical technique for the...

We treated 21 patients with 22 dislocations of the knee by repair or reconstruction of all injured ligaments. Eight knees were treated in the acute phase (less than two weeks after injury); the remainder were treated more than six months after injury (6 to 72). Reconstructions were carried out with a combination of autograft and allograft tendons and by direct ligament repair where possible. At...

Purpose: To analyze the results of the use of intra-articular cultured autologous bone marrowederived mesenchymal stem cell (MSC) injections in conjunction with microfracture and medial opening-wedge high tibial osteotomy (HTO). Methods: Fifty-six knees in 56 patients with unicompartmental osteoarthritic knees and genu varum were randomly allocated to the cell-recipient group (n 1⁄4 28) or cont...

The purpose of this study was to evaluate long-term outcome, following microfracture of the knee in a large patient group, using a random-effect model for longitudinal data analysis. There were 350 subjects (males, 55%; females, 65%) who underwent knee microfracture by a single surgeon between 1992 and 2002. Mean age was 48 years (range, 12-76 years). Subjective questionnaires were collected fr...

INTRODUCTION The aim of the study is retrospectively investigated durations for returning to work following anatomic ACL reconstruction by hamstring autograft in miners and the reasons in patients who were delayed to return to work. METHODS Miners with symptomatic anterior cruciate ligament rupture underwent arthroscopic reconstruction. Patients were evaluated in terms of range of motion (ROM...

We identified a series of 128 patients who had unilateral open reconstruction of the anterior cruciate ligament (ACL) by a single surgeon between 1993 and 2000. In all, 79 patients were reviewed clinically and radiologically eight to 15 years after surgery. Assessment included measurement of the Lysholm and Tegner scores, the ACL quality-of-life score and the Short Form-12 score, as well as the...

Purpose: The purpose of this study was to report the clinical outcomes of autologous chondrocyte implantation (ACI) procedures performed by a single orthopedic surgeon at a minimum of 7 years follow-up. Methods: A retrospective review of prospectively collected data was performed on 29 patients who underwent ACI of the knee between the years of 1998 and 2003. Prospective data were collected to ...

BACKGROUND Quadriceps tendon-patellar bone (QTPB) autograft is an excellent graft option with good clinical outcome. Use of QTPB autografts have increased because they minimize donor-site morbidity including anterior knee pain, while providing adequate mechanical strength. Although, there were many clinical results about allografts that used in anterior cruciate ligament (ACL) reconstruction, i...
